8-channel Current Input Module using the DCON Protocol (fast sampling version). The I-7017C is an 8-channel current input module that is specifically designed to measure current only. Its user-friendly design saves both time and effort when measuring a current thanks to a built-in resistor, meaning that you can now measure current directly. The I-7017RC is an upgraded version of the I-7017C, with the only difference being that the I-7017RC is muc..
